[0043] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following describes the technical solutions in the embodiments of the present invention clearly and completely in conjunction with the drawings in the embodiments of the present invention:
[0044] The present invention considers the method of cyclic shifting the residual image histogram to adaptively calculate the optimal binarization threshold of the residual image, so as to perform the binarization operation on the residual image, and the result obtained is the final binary value of the original image The result image. In this embodiment, the implementation process of the method of the present invention will be specifically explained by taking the detection of a sea surface target in an infrared sea surface image as an example.
